Mycobacterium tuberculosis is a slender and slightly curved bacterium with a size of 1-4X0.4 μ m. Mycobacterium bovis is relatively thick and short. The lipid content of bacterial cell walls in the genus Mycobacterium is relatively high, accounting for about 60% of dry weight. A large amount of mycolic acid surrounds the peptidoglycan layer, which can affect the penetration of dyes. Mycobacterium is generally stained with Ziehl Neelsen acid fast staining method, which can be stained with 5% carbolic acid and heated, but it is not easily decolorized with 3% hydrochloric acid ethanol. If methylene blue is added for counterstaining, the mycobacteria will appear red, while other bacteria and substances in the background will appear blue.

Mycobacterium tuberculosis can be induced by penicillin, cycloserine, or lysozyme in vitro and in vivo, which can affect the synthesis of peptidoglycan in the cell wall. Isoniazid affects the synthesis of mycolic acid. After macrophages engulf Mycobacterium tuberculosis, the action of lysozyme can destroy peptidoglycan, leading to its transformation into L-type bacteria in granular or filamentous form. Isoniazid affects the synthesis of mycolic acid and can become acid fast staining negative. This polymorphic staining pattern is commonly seen in specimens of tuberculosis infection both inside and outside the lungs. Non acid Gram positive granules, formerly known as Much granules, can even be seen in clinical tuberculous cold abscesses and sputum specimens. This particle can return as an acid resistant bacterium in vivo or cell culture, therefore it is also an L-type bacterium.  [2]
